Cantilevered support system for structures

ABSTRACT

A structure such as a house provided with a support system supporting it in overhanging relation to a hillside, the system having a concrete abutment inset in the hillside but having an outwardly exposed lateral face, bearing pilings for the abutment, anchor rods and a deadman anchor further stabilizing the abutment, and a hollow cantilevered support pad tied to the exposed face of the abutment and extending horizontally over the hillside to constitute a support pad for the structure and define storage space, for example, for septic tank, utilities and storage purposes.

INVENTORS EUGENE P COLL/N5 IE' BY CARL W DNEK TTOKNEVS v steepness ofterrain.

Another object of the invention is to provide a cantilevered support padfor supporting a structure in overhanging relation to a hill withoutrequiring direct underpinnings.

A further object of the invention is to provide a support pad of thetype described in the form of a structural shell to delineate subjacentspace for storage and other purposes in relation to the structure.

Other objects and advantages of the invention will be apparent from thefollowing description taken inconjunction with the drawing forming partof this specification, and in which:

FIG. 1 is a view in perspective of a structure and the structure supportsystem of the invention;

FIG. 2 is a view in vertical cross section of the support system;

FIG. 3 is a view in front elevation of the support system; and 7 FIG. 4is an enlarged detail view taken along lines 4-4 of FIG. 2.

Referring to the drawing, a structure 10 is shown supported inoverhanging relation to hillside 12 by the support system of theinvention. This system comprises an elongated concrete abutment 14,bearing pilings -16, deadman anchor 18, connector rods interconnectingabutment l4 and anchor 18, and a tapered cantilever beam indicatedgenerally at 22 secured by connector rods 24 to abutment 14. Beam 22 isin the form of a structural shell comprising upper and lower walls 26and 28, inner and outer walls 30 and 32, diaphragm members 34interconnecting these various walls, and bridging members 36interconnecting the upper and lower walls 26 and 28 and adjacentdiaphragm members 34. Diaphragm members 34 divide the interior of beam22 into a pre-selected number of compartments for such as septic tank,utilities and storage usage. Preferably the diaphragm members 34 formthe side members of individual modular units suitably dimensioned fortransportation by trucks.

It will be appreciated that if the hillside earth were removed from allabout the support system, except for the footings of the pilings 16, thestructure 10 would still be stably supported by an adequate safetyfactor, the pilings 16 being sufficient in number and strength tosupport the weight of the whole system, including the structure, and toeffectively resist the torque applied to abutment 14 by beam 22 andstructure 10, and the anchor 18 and connectors 20 serving to apply anoff-setting counter-torque to the abutment 14. Of course, the presenceof the earth, i.e. earthen enclosure means of the hillside in coveringor supporting relation to the elements of the support system increasesthe potential resistance to movement of the support system, but theearth can be looked upon as furnishing the means for physical access tothe otherwise stably supported structure.

It will be appreciated that the concrete pilings l6 constitute onespecies of support means for the abutment 14, another being bed-rockwhen available.

What is claimed is:

1. In combination, an abutment having upper, lower, rearward and forwardsurfaces, support means connected to and extending downwardly from theabutment, a deadman anchor disposed rearwardly of the abutment andconnected thereto by connector rods, earthen 'nclosure means for thesupport means, connector rods, anchor and the rearward and lowersurfaces of the abutment, said forward surface of the abutment beingfree of said enclosure means, and a platform attached to the forwardsurface of the abutment and extending therefrom.

2. The combination of claim 1, said forward surface of the abutmenthaving at least a portion thereof which is inclined downwardly andrearwardly out of a vertical plane.

3. The combination of claim 1, said platform comprising a plurality ofinterconnected and disconnectable cell-like modular units.

4. The combination of claim 1, said platform having upper, lower,rearward and forward surfaces, the platform rearward surface beingcomplemental to and in engagement with the abutment forward surface, theplatform upper surface being substantially parallel to and level withthe abutment upper surface, the platform lower surface being inclinedupwardly and forwardly from the platform rearward surface to theplatform forward surface.

5. The combination of claim 4, including a structure mounted upon andattached to the platform upper surface, said platform beingsubstantially hollow and having internally disposed reinforcement andpartitioning means defining at least in part service compartments forthe structure.

6. The combination of claim 1, said platform being in the form of asubstantially hollow structural shell attached to the forward surface ofthe abutment, a structure mounted upon and attached to the platform,said platform having internally disposed reinforcement and partitioningmeans defining at least in part service compartments for the structure.
